Improvement in bob-sleds



PATENT FFICE.

JOHN WAMPAOH, OF SHAKOPEE, MINNESOTA.

IMPROVEMENT IN BOB-SLEDS.

Specification forming part of Letters Patent No. 124,522, dated March 12, 1872.

Specification describing a new and useful Improvement inBob-Sleds, invented by J OHN WAMPACH, of Shakopee,in the county of Scott and State of Minnesota.

The invention will rst be fully described, and then be clearly pointed out in the claim.

Figure l is partly a side and partly a sectional elevation of a pair of bob-sleds constructed according to my improvement. Fig. 2 is a top or plan view, and Fig. 3 is a rear elevation. Y

Similar letters of reference indicate corresponding parts.

A represents the chain by which the tongue B and the front beam C are connected together7 the object of which is to apply the draft directly to the beam instead of through the runners, as heretofore, and to do it in such manner as to allow the runners to vibrate freely as much as required without twisting or cramping the connecting device, as it would be if a rod or any rigidly-arranged connection was used. D

represents the reach which connects the' two bolsters E, which I propose to make in two parts and joint them together, as shown at F, so that they may Work vertically and horizontally, to allow the bobs to work more freely in running over uneven ground. Hrepresents the T-bars, used to strengthen the connection of the knee-posts with the braces I for further strengthening the knees in the lengthwise direction of the sleds, in which they are exposed to very great strains.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The iiexible connection A, combined intermediately with the tongue B and front beam O, as and for the purpose set forth.

JOHN WAMPACH.
